. >> president obama, his last campaign promise to the american people, the final debate, this is what he said about sequester. >> first of all, sequester is not something that i proposed. it's something that congress has proposed. it will not happen. >> he said it will not happen. you're preparing for it to happen. it seems paul ryan was just on "meet the press" last week and he said it's more likely to happen than not. in your view, is this going to happen? >> in a world of responsible politics, it should not happen. >> ok. we don't live in that world right now. are you assuming it's going to happen? >> look, we've got to plan for that possibility. because there are so many members that are saying we're going to let it take place. but i have to tell you, it is irresponsible. for it to happen. i mean, why in god's name would members of congress elected by the american people take a step that would badly damage our national defense? but more importantly, undermine the support for our men and women in uniform. why would you do that? >> general dempsey, you have said this would be catastrophic.
